Patent BR-0108390-B1 (BR)
Inventor: VAN LOO JOSEPH HUBERT
IPC: B02C23/04
Filed: 2001-02-14
Abstract: A method and two apparatuses for comminuting chips are presented. Chip breakers without a coarse-part ejecting element are often used for comminuting chips. Blocking constituents therefore have to be removed with great effort, for example by hand. If a coarse-part ejecting element is present, there is no differentiation between blocking hard parts and blocking clumps of chips, but instead both types are ejected. It is now envisaged to subdivide blocking constituents in horizontal chip breakers into categories, depending on the negative acceleration of the shaft (3, 17, 18) caused by the blocking, and to assign to each category a defined reversing operation for loosening the blocking constituents and, if appropriate, discharge from the comminuting space (1, 15) by means of a coarse-part ejecting element (12, 32).

Filed: 1997-09-23
Abstract: Water-soluble macromers including at least one hydrolysable linkage formed from carbonate or dioxanone groups, at least one water-soluble polymeric block, and at least one polymerizable group, and methods of preparation and use thereof are described. The macromers are preferably polymerized using free radical initiators under the influence of long wavelength ultraviolet light or visible light excitation. Biodegradation occurs at the linkages within the extension oligomers and results in fragments which are non-toxic and easily removed from the body. The macromers can be used to encapsulate cells, deliver prophylactic, therapeutic or diagnostic agents in a controlled manner, plug leaks in tissue, prevent adhesion formation after surgical procedures, temporarily protect or separate tissue surfaces, and adhere or seal tissues together.

Abstract: Injection molding apparatus with each elongated cooled mold core (10) having a hollow elongated inner part (78) inside a hollow elongated outer part (80) and an integral dome shaped front cap (132). The outer surface (120) of the inner part (78) and the inner surface (126) of the outer part (80) each having cooling fluid conveying grooves (122, 128) which spiral in opposite direction. This provides very uniform cooling and forces the cooling fluid flow through the grooves (122, 128) to be very turbulent which increases cooling efficiency. It also gives the mold cores (10) additional structural strength to withstand higher injection pressures.
